OpenCL fails to build on OSX Mavericks 10.9.1: c2hs cannot parse resource.h

[burtonageo]

On my machine, I cannot seem to be able to install OpenCL, as the following error appears:

Georges-MacBook-Pro:Downloads georgeburton$ cabal install opencl
Resolving dependencies...
Configuring OpenCL-1.0.3.4...
Building OpenCL-1.0.3.4...
Preprocessing library OpenCL-1.0.3.4...
c2hs: C header contains errors:

/usr/include/sys/resource.h:349: (column 75) [ERROR]  >>> Syntax error !
The symbol `=' does not fit here.

Failed to install OpenCL-1.0.3.4
cabal: Error: some packages failed to install:
OpenCL-1.0.3.4 failed during the building phase. The exception was:
ExitFailure 1

My GHC version is:
The Glorious Glasgow Haskell Compilation System, version 7.6.3

And my cabal version is:
cabal-install version 1.18.0.2
using version 1.18.1.2 of the Cabal library

I apologized, I cann't test it nor prepare a fix. If someone can send a patch, I'll put in the hackage.

What is the best way to dig deeper into cabal build problems? I'd like to know what's going on

[zhensydow]

Well, the best way to test it is with a clone of the source repository instead of install the cabal package.

git clone git@github.com:IFCA/opencl.git

Or maybe with a fork. And then try get a fix it in your computer.

If the fix is founded and don't break current working versions (i'll test on linux) I can upload it to hackage.

I have exactly the same problem.

I just ran into this as well. The problem is that c2hs uses Language.C to parse headers and sometimes it's buggy or missing support for vendor specific extensions. Using a different FFI tool like hsc2hs would prevent problems like this. That's because hsc2hs uses gcc to process any C files and headers.

[zhensydow]

I should try to switch to hsc2hs, but currently I don't have too much time.

This is now haskell/c2hs#85.
